弹出菜单中的文字颜色即使样式也没有改变。相对于styles.xml中的颜色，背景颜色正在变化，但是文本颜色和文本大小没有反映出来。

//Creating the instance of PopupMenu  
PopupMenu popup = new PopupMenu(mContext, holder.im_overflow);      
//Inflating the Popup using xml file  
popup.getMenuInflater().inflate(R.menu.list_overflow_menu, popup.getMenu());     
//registering popup with OnMenuItemClickListener  
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {      
    @Override
    public boolean onMenuItemClick(MenuItem item) {
        if( item.getTitle().equals("Edit")){
            callEdit();
        } else if( item.getTitle().equals("Export")) {
            callShare();
        } else if( item.getTitle().equals("Delete")) {
            callDelete();
        }
        return true;
    }
});

popup.show();

Styles.xml

<style name="AppBaseTheme" parent="@android:style/Theme.Light.NoTitleBar">
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:popupMenuStyle">@style/PopupMenu</item>      
</style>

<style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
    <item name="android:popupBackground">@android:color/white</item>
    <item name="android:textColor">#FF01F0</item>
    <item name="android:textSize">12sp</item>
</style>

但这并没有改变文本的颜色。

您可以通过将此代码添加到styles.xml并在清单文件中使用它来更改文本大小和颜色。对我来说，它奏效了。

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:popupMenuStyle">@style/PopupMenu</item>
    <item name="android:textAppearanceLargePopupMenu">@style/myPopupMenuTextAppearanceLarge</item>
    <item name="android:textAppearanceSmallPopupMenu">@style/myPopupMenuTextAppearanceSmall</item>
</style>

<style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
    <item name="android:popupBackground">@android:color/white</item>
    <item name="android:textColor">#FF01F0</item>
    <item name="android:textSize">12sp</item>
</style>

<style name="myPopupMenuTextAppearanceSmall" parent="@android:style/TextAppearance.DeviceDefault.Widget.PopupMenu.Small">
    <item name="android:textColor">#545656</item>
    <item name="android:textSize">15sp</item>
</style>

<style name="myPopupMenuTextAppearanceLarge" parent="@android:style/TextAppearance.DeviceDefault.Widget.PopupMenu.Large">
    <item name="android:textColor">#545656</item>
    <item name="android:textSize">25sp</item>    
</style>
